This study describes the influence of distributed generation (DG) on a double‐ended fault location based on measuring the high‐frequency fault transients. The additional non‐fundamental frequency current components from DG will influence the accuracy of an impedance‐based fault location technique based on non‐fundamental frequencies. A double‐ended impedance‐based fault location technique that utilises the high‐frequency content (up to 5 kHz) is studied. This study showed that double‐ended method is still able to locate a fault with a maximum error of 4% compared to the case without DG which showed a percentage error up to 2%.
